yeah I don't hate the flop re raise but after that you have to slow down and I think it's marginal. Mostly like juan said you're helping worse hands to get away. Also note there are a ton of cards that will kill your action or beat you even if he does have Ax

Def as played once you bet the turn you're committed on non A/J/T rivers .

If he had AK/AQ/JT or a set then that's just a cooler.
What range are you giving him to call a flop 3 bet?
